Use both context and class' class loader when reading component metadata ------------------------------------------------------------------------ Key: ISPN-3032 URL: https://issues.jboss.org/browse/ISPN-3032 Project: Infinispan Issue Type: Enhancement Reporter: Mircea Markus Assignee: Mircea Markus Priority: Minor {quote} Caused by: org.hibernate.search.SearchException: Unable to initialize directory provider: org.hibernate.search.test.integration.jbossas7.model.Member at org.hibernate.search.store.impl.DirectoryProviderFactory.createDirectoryProvider(DirectoryProviderFactory.java:87) at org.hibernate.search.indexes.impl.DirectoryBasedIndexManager.createDirectoryProvider(DirectoryBasedIndexManager.java:232) at org.hibernate.search.indexes.impl.DirectoryBasedIndexManager.initialize(DirectoryBasedIndexManager.java:100) at org.hibernate.search.indexes.impl.IndexManagerHolder.createIndexManager(IndexManagerHolder.java:227) ... 19 more Caused by: org.infinispan.config.ConfigurationException: org.infinispan.CacheException: Unable to load component metadata! at org.infinispan.manager.DefaultCacheManager.<init>(DefaultCacheManager.java:386) at org.infinispan.manager.DefaultCacheManager.<init>(DefaultCacheManager.java:341) at org.infinispan.manager.DefaultCacheManager.<init>(DefaultCacheManager.java:328) at org.hibernate.search.infinispan.CacheManagerServiceProvider.start(CacheManagerServiceProvider.java:93) at org.hibernate.search.engine.impl.StandardServiceManager$ServiceProviderWrapper.startVirtual(StandardServiceManager.java:178) at org.hibernate.search.engine.impl.StandardServiceManager.requestService(StandardServiceManager.java:124) at org.hibernate.search.infinispan.impl.InfinispanDirectoryProvider.initialize(InfinispanDirectoryProvider.java:86) at org.hibernate.search.store.impl.DirectoryProviderFactory.createDirectoryProvider(DirectoryProviderFactory.java:84) ... 22 more Caused by: org.infinispan.CacheException: Unable to load component metadata! at org.infinispan.factories.components.ComponentMetadataRepo.initialize(ComponentMetadataRepo.java:131) at org.infinispan.factories.GlobalComponentRegistry.<init>(GlobalComponentRegistry.java:103) at org.infinispan.manager.DefaultCacheManager.<init>(DefaultCacheManager.java:381) ... 29 more Caused by: java.lang.NullPointerException at org.infinispan.factories.components.ComponentMetadataRepo.readMetadata(ComponentMetadataRepo.java:53) at org.infinispan.factories.components.ComponentMetadataRepo.initialize(ComponentMetadataRepo.java:129) ... 31 more {quote} The exception above is caused by Infinispan using (by default) invocation context's ClassLoader when trying to read the component metadata. In a modularized environment such as AS7 this will cause the metadata not to be found (metadata is packaged in the same jar as the infinispan class that reads it). In order to overcome this problem we should try to use both class' ClassLoader and InvocationContxt's class loader when trying to read the metadata. Workaround: set the class loader on the GlobalConfiguration object: {code:java} GlobalConfiguration.classLoader( GlobalConfiguration.class.getClassLoder()) {code}
